Exhibit L - Reclamation Costs <br />GRADING TRACTS A & C plus 1600.00± feet margin for default: (refer to <br />Exhibit L - Addendum A: Volume Graphic): <br />Assuming a mean depth of basin of 25.0± feet with no walls above the basin. <br />Average push distance is 50± feet using 2 - Cat D8N dozers @ $0.247/LCY <br />Perimeter is 4800.0± feet <br />x Cross-Section Area (Area difference between a 1:25H:1 V slope and a 3H:1 V <br />slope) = 546.88± sq. ft. <br />2,625,024.00± cu. ft <br />27 cu. ft. per cu. yd. <br />97,223.12± cu. yds. <br />x $ 0.19± cu yds. <br />$ 18,472.40± to grade to 3H:1 V @ Tract A & C plus additional 1600.0± feet <br />margin for default <br />RIPPING (none). <br />SUMMARY OF SITE PREPARATION COSTS: <br />$ 14,740.31± Dewatering <br />$ 18,472.40± Grading Tracts A, C, plus Default <br />$ 33,212.71± Total Site Preparation Prior to Re-soiling. <br />Soil Demand AND Re-soiling of Affected Lands (refer to Exhibit I & J - Table <br />I-1: Soil Volumes): <br />NOTE: The soil demand (and related costs) will decrease proportionately as <br />extraction activities increase over each Tract of planned extraction. For now, an <br />area estimate of 22.57± acres (default area) will be determined for resoiling <br />expenses. At a depth of 0.5± feet, the total volume = 22.57± acres x 0.5± feet of <br />soil replacement x 43,560.0± sq.ft./acre - 27 cu.ft./cu.yd. = 18,214.54± cu.yds. <br />total soil requirement. <br />The majority of soil placement can occur using the an average placement distance <br />of 600 ft. a the plant site location, or less along embankments, utilizing a Cat 637E. <br />Varra Companies, Inc.
